This wide-ranging anthology uncovers the hidden histories and ideas of community armed self-defence, exploring how it has been used by marginalised and oppressed communities as well as anarchists and radicals within significant social movements of the twentieth and twenty-first centuries. Far from a call to arms, or a 'how-to' manual for warfare, this volume offers histories, reflections, and questions about the role of firearms in small collective defence efforts and its place in larger efforts toward the creation of autonomy and liberation.
